Abstract
Thin films of copper selenide (CuSe) were chemically deposited onto a glass substrate. We studied optical properties which include absorbance, reflectance, transmittance, refractive index, using a Janway 6405 UV/Visible spectrophotometer. Surface morphology of the films were carried out using an Olympus Optical microscope. A bandgap of 2.2eV and refractive index of 2.5 was obtained for CuSe thin film.
